Perhaps because no important information is represented in absolute brightness values in the visual environment, the visual system has confined its processing almost exclusively to differences – spatial and temporal contrasts. Recording from neurons along the visual pathways shows that the cells have structured receptive fields – defined angular positions in the visual field where they respond to the stimulation.
